Feed pump

A fuel pump is developed as a side-channel pump with two conveyor chambers for the conveying of a liquid to an outlet channel, and has two inlet channels arranged one behind the other seen in the direction of flow. One of the inlet channels debouches into a radially inwardly arranged partial-ring-shaped channel, while the other inlet channel is connected to a radially outwardly arranged partial-ring-shaped channel. In this way, the pressure within the liquid to be conveyed is increased stepwise and, thus, gas bubbles produced by a vaporization of the liquid are avoided.
